Accessibility often isn’t a priority for companies as they grow, but if you don’t invest in it early it can become a knotty problem. In this talk Mallika will share how to break down a complex Android application to find low-hanging fixes as well as prioritizing larger improvements and investing in accessibility in the future. She will explore her experience growing grassroots support for accessibility improvements at companies and both the moral and business value of improving it.

Mallika is an Android developer at Thumbtack where she works on helping people find local skilled professionals for any project they could imagine. She is passionate about accessibility engineering and inclusive design, as she firmly believes technology should connect and be inclusive of everyone.

One of the best ways to guard against exploitation is to analyze your application in the same style as a black hat hacker. Data leaks, insecure storage and a slew of other vulnerabilities are all identifiable simply by reverse-engineering an APK. In this talk, we’ll walk through how to get started with auditing your own applications: reversing the APK, analyzing the reversed source & finding areas that could be vulnerable to attack. We’ll also cover tools and shortcuts for automating some of these tasks.

Constraint Layouts, Fragments, Data Binding, Architecture Components. The continuous release of new abstractions and paradigms can be a draining process for even the most experienced programmers. For this talk I focus on the Zen like process of leaving it all behind, and stripping away layers, rather than adding them. Android has always provided all the tools you need, you just need to know where to look for them. I talk about the Canvas and how you can draw fast and complex views, the Android Layout System and how you can implement custom responsive layouts, and using the Touch Event System to create smooth gestures across view boundaries. This talk is applicable for every level of Android developer. Familiarity with a programming language is the only prerequisite.

Every engineer has great intentions when diving into a codebase. You want to make the code beautiful, easy to read, and modular. However as time passes and new feature and quick bug fixes are put in, somehow your android codebase turned into a mess of multiple levels of inheritance of views and fragments and you're stuck wondering how you ended up here in the first place.

In my talk I will share with you common poor patterns that every developer first makes when developing in android and the alternative architecture patterns to ensuring clean code. We will talk about listeners, event driven paradigms and clean architecture.

Your relationship with RxJava doesn't have to be complicated. We find many ways to use it wrong; it is also powerful when used properly. In fact, RxJava can guide you in shaping a sound architecture for your app. We only have to follow a few but decisive principles.

In this talk, we'll:

• See at how side-effect isolation can help avoiding bugs.
• Learn how to share one unique stream between your view and your presenter.
• Discover the ways a unidirectional data flow makes adding new functionality easy and safe.
• Look at how data immutability brings safety to data manipulation.

After this talk, you’ll be able to write a robust and reactive architecture for your app, taking full advantage of RxJava.

Reliable multiplatform development has been the Holy Grail for Mobile Developers since its inception. Many frameworks did appear and disappear. Kotlin/Native has come strongly, and since it is still in Beta version there are some caveats about this. Is Kotlin/Native reliable for my app? Is it production-ready?

Come to this talk to learn what Kotlin/Native can do for you.

In this talk we will discover how we can use just Kotlin features to inject dependencies through our codebase. Using this novel approach we'll introduce the concept of Type Classes, a unit of abstraction and configuration used to architect apps and libraries.

Have you been thinking about modularizing your app, but haven't found the incentive to do so yet? That will change in this session where you will learn to use dynamic app modules to split your monolith into logical features—each of which can be downloaded independently, thus saving users’ data. Learn tips and tricks on building, testing, and deploying your dynamic features. By the end of the session, you will be familiar with the structure of a dynamic app, know how to communicate between the different feature modules, and be able to effectively use the internal track to test them.

Alex is a passionate open source Android developer. He loves to build apps with Firebase and contribute to numerous libraries. Notably, he's the co-author of FirebaseUI Android, Gradle Play Publisher, Easy Permissions, and LicenseAdapter. Whenever something is broken or can be improved, he prefers to go ahead fix it while learning how the technology works rather than add to the maintainers’ backlog.

He also loves participating in alpha and beta tests to experience the bleeding edge of unreleased software and play with something new.

When he isn’t slowly losing his eyesight in front of a computer screen, he likes to go on hikes and camping or bikepacking trips out in nature to find fresh air and photo opportunities.
